Target	640 nM (M2 muscarinic acetylcholine receptor in rabbit peripheral lung), 386 nM (M2 muscarinic acetylcholine receptor in rat heart)[1].
In Vivo	Otenzepad (0.5, 1 mg/kg, s.c., in rats) significantly improved win-stay acquisition relative to vehicle-injected controls[2]. Otenzepad (2 mg/kg, s.c., in rats) significantly improved retention relative to vehicle controls[2]. Otenzepad (0.3, 1.0, or 3.0 mg/kg, ip, in mice) potentiates the effects of glucose and reverses the effects of insulin on memory[3]. Animal Model: Forty-eight male Long-Evans rats (325-350 g)[2]. Dosage: 0.25, 0.5, 1.0 and 2.0 mg/kg. Administration: S.C. on the dorsum of the neck once. Result: Doses of 0.5 and 1.0 mg/kg significantly improved acquisition relative to vehicle controls, while doses of 0.25 and 2.0 mg/kg had no effect. Animal Model: Adult male Swiss mice (age 60–70 days; weight 25-30 g)[3]. Dosage: 0.3, 1.0, or 3.0 mg/kg. Administration: IP once. Result: Enhanced retention in an inverted-U dose–response manner, with significant enhancement seen at 1.0 mg/kg (U15,15 = 49, p < 0.02, compared with saline-saline-injected control group).
